parts needed
2- empty d-cylinder Oxygen tanks - $80 rated ~2500+psi
1- Truck Air pump $45
2- brass All-tube T's 1/4" $4 each
2- 1/4" tube to 1/8" NPT compression 90 degree $2 each
1- 1/4" tube to 1/8" NPT compression Straight $1.50 each
1- 1/4" tube to 1/4" NPT compression Straight $1.50 each
1- 1/8" NPT to Schrader valve for water heater $4.50 each
~3 ft- of 1/4" Poly Tubing ~$.45
25 Ft- of 1/4" Poly Tubing ~$1.50
1- Size R drill bit, $2
1- 1/8" Morse NPT TAP, $12.50 (WORTH EVERY PENNY)
2-1/8" NPT insert plugs (for painting the tanks)
I used the 3 ft of poly tube for assembly, and the 25 ft is for running around the truck for airing up my tires. basically use the first T to hook the 2 tanks together, and start the run to the compressor, the second T is for the 25 ft line to get around the truck and completes the run to the 1/4" tube to 1/8" NPT compression Straight for the schrader valve. the schrader valve is to keep the Truck Air stock, so it keeps its manufacturers 5 year warranty
Prepping the tanks...
Well I basically tried to use brute force to get them off. after about 3 weeks of fighting it, I just cut the valve at the top of the tank, it leaves about an 1/8 hole, a size R bit is about 21/64 give or take. This took 1 minute with a fresh blade, and I wouldn't recommend wasting the effort of removing them, since the tank may, or may not be 1/2" or 3/4" NPT. I then used several drill bits to step up to the Size R bit and tapped the hole, I then blew the shavings out with my house compressor. the NPT fittings are put in with teflon tape, the red and white container (thicker, slightly more expensive, but SOooo much easier to work with than blue and white) the compression fittings were dabbed with pipe thread compound/PFE paste. I'm leaving out that I took the time to wire wheel the green paint/sticker glue off and scuffed it up to take a coat of primer and a burgundy paint, because its not necessary for fab work.
I will have pics posted tonight!
